GLAZED STRUCTURE.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed March 18, 1904. Serial No. 198,869.

To all whom it may concern;

Be it known that I, ROBERT N. SCHALKEN- BACH, a citizen of the United States, residing in Jersey City, Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Glazed Structures, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a perspective View, partly in section, showing the main features of my invention. Fig. 2 is a cross-section of one of the lateral joints. Fig. 3 is across-section of the main cap to show its shape before being clamped down upon the astragal. Fig. 4 is a section with one of the lateral gutters in elevation. Fig. 5 is a front elevation of the edge of the roof, the expansion-clip being raised to show the eaves-gutter more clearly. Fig. 6 is a longitudinal elevation of the cap and astragal, the eaves-gutter being shown in section.

My invention relates to systems of glazing wherein the glass is held in place without the use of cement or putty; and the object thereof is to make a construction which shall hold the panes of glass in a'firm but yielding engagement, allow of expansion of the roof under inside pressure, and provide better means for carrying ofl the water of condensation and such water as finds its way between the joints of the structure.

In accomplishing these objects I use the construction shown in the drawings, wherein A indicates one of a number of main supporting bars or astragals, designed also to form the main gutters for the carrying off of the water. They are arranged at suitable distances apart and extend downwardly toward the bottom of the sloping roof. These astragals are .L- shaped in cross-sections, having a central web a and two side gutters a with longitudinal flanges (4 The astragals are supported in any suitable manner.

B is a cap which is made in one piece or in sections joined together and which runs the whole length of the astragal. The cap is of approximately triangular section, with sides which are outwardly and downwardly flared from the apex and is held down upon the panes of glass C by the bolts A and nuts (4 as clearly shown in Fig. 3. The inturned bearing-faces a of the cap have downwardlyextending flanges (5", which normally fit against the edge of the panes C. In order that these flanges and the inturned bearing-faces (0* may be forced into conformity with and held tightly against the glass and against the packing-strip D, I make the cap originally with a greater angle between the sides and the bearing-face (4* than it is intended to have when in position, and then bend the bearingface (0 into its proper position by screwing down the nuts (f. In Fig. 3 I have shown the original form of the cap in full lines and in dotted lines the form it takes after compression. v

D is a packing-strip, of any suitable material, preferably lead, which will conform to the irregularities of the glass.

The effect of screwing down the nuts a upon the cap B is to force outward the flaring sides of the cap, and thus draw the downwardly-turnedflanges a outward against the edges of the panes. By this means the caps on either end of a pane may at any time be adjusted so as to tighten the lateral hold on a pane held between the flanges. This construction also enables not only the cap at any time to be forced downward on the pane with greater force, but also enables the downwardly-turned flange a to be tightened against the pane from the outside, an advantage not found in caps where the tightening of the astragal-bolts simply force the cap downward.

The side flange ra -supports on its upper edge the condensation-gutter E, which fits over the said flange and has at its opposite side the upturned elastic edge c. This edge is formed by bending the material of the gutter sharply upward in an approximate V shape. The end of this V-shaped bend is slightly turned outward and forms by its springiness a yielding seat for the glass and at the same time a close-fitting joint to prevent dust from entering the condensationgutter E.

F is a lateral gutter running from one astragal to another underneath the lateral joints between the panes of glass.

As shown clearly in Fig. 4, the gutter F is made with a bottom inclined downwardly from its middle at f toward its ends. As shown also in Fig. 4, the astragal-flange a is cut away for the reception of the end of the gutter F, so that the contents of the gutter will empty into the gutter a. The upper flange of gutter F is also cut away at f for the reception of the condensation-gutter E. It will thus be seen that the condensationgutters empty into the lateral gutters, these into the astragal-gutter, and by the astragal- IIO 7 shown in Fig. 5, to let the clip and astragal gutter the water is carried downwardly and l out through the opening 7'; in the expansionclip K. (Shown in Fig. 5.)

The lateral joining of the panes of glass G C, I accomplish as shown in Fig. 2.

G is a joint-clip formed of a strip of metal the length of the joint, having a right-angular bend g, which fits the edge of the lowermost pane G. The vertical web g is deeper than the thickness of the glass and is at its bottom bent upward at an angle to form aseat for one pane. The metal is then bent downwardly back on itself to a line beyond the vertical web 9 and then upwardly underneath the other pane of glass, where it is slightly rounded to form a seat 9 represents putty, cement, asbestos, or other suitable packing material, which fills the space between the clip, the edge of the glass, and the angular bend below. A joint-clip made as shown will not leave the glass when pressure is applied to the panes. Pressure on either panes forces the opposite seat more strongly against the other. It also provides a spring-seat for the panes. This result has never before been accomplished, as far as 1 know, in any joint heretofore described.

I do not provide any lateral gutter F for the lowermost condensation-gutters E; but, as shown in Fig. 6, the water therefrom empties into the eaves-trough H, which is pierced at its bottom, as at it, to allow the Water to flow off.

The eaves-trough has a rearward extension it, which fits between the eaves-nailing piece I and the expansion-clip K. The forward side of the trough is bent upward at if to the plane of the glass C and then bent outward to form a seat k for the glass. Where the trough meets the projecting end of an astragal and its expansion-clip K, its face 71.2 is cut out, as

project through the same. Thus, as will be seen in Figs. 5 and 6, the eaves-trough is continuous under the astragal at the front, as at 7L4, Fig. 5, and at the rear extension h.

The advantages of my glazing system are obvious.

The cap B has a broad seating on the glass and the method of putting it in place allows it to conform to irregularities in the glass or lead strip D. The free edge of the inturned portion of the cap has also a yielding and elastic bearing on the glass, allowing for any vertical vibration of the glass along its length, the downwardly-turned edge a also preventing shifting of the glass laterally.

The under seat of the pane, by reason of the upturned edge e of the condensation-gutter, is also yielding and not only presses constantly against the under surface of the pane, but also rises with the rise of the edge of the pane under vibration. This same principle of giving an elastic or yielding seat to the glass is carried out in the lateral joints Where pressure on one pane is taken by the spring-clip G, which is always in contact with the glass.

By using the oppositely-inclined side gutter F the water is prevented from accumulating in the same, as it will do when the bottom of the gutter is horizontal.

By making the eaves-trough in one piece and carrying it under the expansion-clip K and astragal it is held more securely in position and prevented from shifting.

While I have shown what I believe to be the preferable form of my invention, 1 do not mean to limit myself to the exact details or to the exact arrangement shown herein, as there may be many modifications without departing from the spirit of my invention.
